Be it known that I, EDUARD GRossE, residing at No. 1 Elsastrasse, Reud nitz, near Leipting the edges of books, provided with mechanism for feeding the books and a device for holding the latter and with mechanism for automatically delivering the books.

Fig.6 is aside view thereof, showing the shafts, &c., in section. Fig. 7 isa front view of the cutting mechanism. Fig. 8 is a side view thereof. Fig. 9 is a front view, and Fig. 10 a side view, of a cutting-support. Fig. 11 is a front view, and Fig.12 a transverse section, of the mechanism for coloring the cut edges of the books. Fig. 13 is a rear view, and Fig. 14 a side view, of the delivering mechanism. Fig. 15 is a diagrammatic elevation of the gearing indicated in Fig. 2, showing particularly the relative positions of the mutilated gears, hereinafter described, and of the teeth occupying one-half of the peripheries thereof.

In machines as used at present for cutting the edges of books the books are .pushed in under the knife and are taken out again, which is tedious and dangerous to the operator. In the machine described hereinafter the books are 'fed quickly and without danger into the receiver of a rotary' feeding device at the side of the knife.

The rotary feeding device consists of a middle part and four receptacles or receivers A, A A and A, Fig. 2. It is rotated in the direction of the arrow and makes a quarterrevolution at each movement and then comes to rest. When the feeding device is at. rest, the cutting, coloring, and delivery mechanisms come into operation. The book received by the rotary feeding device is carried step by step completely around the machine. During the first quarter-revolution it is carried from A to A". At A is situated the cutperipheries. A spur-wheels 7L and 9 only during one-half ofting device B, which cuts the book while the feeding device is at rest. During the second quarter-revolution the rotary feeding device carries the book from A to A where the edges are colored or printed by the coloring device 0, which does not form a part of the present invention. ried to A where the discharging device E effects automatically the delivery of the book. (See Fig. 2.) While the first book is carried through the machine in the manner described another book is inserted at A at each quarter-revolution in the next receptacle or receiver of the rotary feeding device. The latter, therefore, contains three books after a complete revolution,which are operated upon by the cutting, coloring, and delivering devices while the feedi'hg device is at rest, and a fourth book is inserted at A. There- Thence the book is carfore the rotary feeding device and the col- 1 oring and delivering devices move and come to rest alternately. This alternating motion is eifected by the gearing shown in Figs. 1 and 2 and also in Figs. 3 and 4. The machine is first driven by a pulley U, which is disengaged and engaged through a frictioncoupling by means of a lever w, a draw-bar w, and a treadle 10 (See Fig. 1.) A flywheel a: is situated at the side of the pulley n. Pinion a engages with spur-wheel I A counter-shaft c, engaging with a spur-wheel d, is situated on the same axle as spur-wheel b. Spur-wheels e andf are situated on the same axle as the spur-wheel d, the wheel 6 engaging with a spur-wheel h and the wheel f with the spur-wheel g. The wheels e and f are provided with teeth on only one-half of their Therefore they rotate on the their revolutions. The rotation being then discontinued,the wheels 72 and 9 come to rest and also the mechanism operated by the latter. The wheel e operates the cutting, coloring, and delivering devices. The wheelf opcrates the rotary feeding device. Phe arrangement is so that the half of the wheel e which'has teeth commences, to engage with the wheel h atthe moment in which the wheel f commences to run empty with its smooth segments. gage with their respective spur-wheels alternately, and the motion and rest of the mech- Therefore the wheels 6 and f en- IOO anism by them alternate in a corresponding manner. The rotary feeding device is operated by means of the carrying-wheel g, which drives a large spur-wheel Z, situated on the axle of the rotary feeding device and which is twice as large as the spur-wheel f. Consequently the spur-wheell makes only half a revolution, while the spur-wheel f makes a whole revolution. Further, as the wheelfis provided with teeth on only one-half of its circumference it must make four revolutions in order to rotate the axle ofthe wheell oncet'. e., while the wheel f makes one revolution the wheel 1 and the feeding device, rotating with it, make only a quarter-revolution and are at rest while the smooth segment of the wheel fruns empty. In the same manner the other wheel e, provided with teeth on only one halfof its circumference, effects the alternating operation of the other mechanisms. The wheel 6 operates the spur-wheel h at the same moment in which the rotary feeding device comes to rest. The wheel h is situated on the same axle as a bevel-wheel t', which operates a bevel-wheel k. The latter carries a crank-disk h, which etfects the ascent and descent ofaknife B (See Fig. 2. The bevelwheel k is only half as large as bevel-wheel 'i, which makes onlyhalf a revolution in a corresponding period to that of the wheel is, so that the crank-disk It makes a whole revolution, drawing the knife B down and pushing it up again, during half a revolution of the wheel 1'. The bevel-wheel vloperates also the coloring device. The former engages with a bevel-whel m, which is only half the size of the bevel-wheel hand is situated on a vertical axle n, the lower end of which carries a bevelwheel 0, which engages-with a bevel-wheel 0, Figs. 2, 11, and 12, which transmits the motion to an axle g by bevel-wheels pp. The axle q carries bevel-wheels 1' 1', which operate a crank-disk 8. To the latter is attached a connecting-rod 2:, which is forced-to follow the rotation and changes the rotary motion into a reciprocating motion, which efiects the reciprocation of the carriage 0, Figs. 2, 11, and 12, with the coloring device and the coloring of the downward edges of the book, which is held at A in the rotary feeding device. The axle q operates also the delivering device E. The former carries a spur-wheel u, Figs. 13 and 14, which engages with a spurwheel u, and thus rotates a crank u which gives an oscillating movement to a lever E and thus etfect-s the delivery of the book in the manner described hereinafter.

' The foregoing gives a general view of the invention. The following-describes. the details shown in Figs. 5 to 14.

Fig. '5 is a plan view of the rotary feeding devicefor the books. Fig. 6 is aside view thereof. The rotary feeding device consists of a body rotating with the axle A and carrying four receivers A A A A, projecting outward, with holding devices. Each receiver is box-shaped and provided with a "pressing-beam which pressesor jams a book in the said receiver. To insure the correct insertion of the books, each receiver is provided with a projecting angle-piece G, Fig. 6, against which the back of the book is placed. The position of the projecting angle-piece G is regulated, as in paper-cutting machines in common use, by a screw G, which engages with a screw-thread of the projecting anglepiece G and moves the latter toward or from the press-beam, according to the rotation of the screw. A pressing-beam H, before mentioned, is provided on each receiver and clamps the book in the' receiver. The pressing-beam H is adapted to move between the sides A of the receiver on tongued guides and can therefore be moved toward or away from the opposite part H, Fig. 6. When a book is to be inserted into the receiver, the pressing-beam H must recede from the part H to allow the book to pass. When the book is to be fixed, the beam H is caused to approach the part H. This is effected by four levers K, situated at each side of the feeding devices and operated by means of rollers K, running on an eccentric or cam L, situated at each side of the frame of the machine. The respective leversK rotate an axle K, on the middle of which is situated a lever K, connected by a swivel-pin K to the pressingbeam H. The lever K moves in accordance with the rise orfall of the lever K on the fixed eccentric L and moves the pressing-beam H toward or away from the part H, thus automatically securing or releasing the book. As the thickness of the books varies and the pressing-beam H travels always the same distance, the difference between distance between the parts-H H of the clamp is regulated to correspond with the varying thickness of the books by the adjusting device H, consisting of a rotatable screw bearing on the jaw H and working in a nut carried by the pressure-arm K, by means of which the pressing-beam H can be adjusted relatively to the part H, according to the thickness of the book to be inserted. The automatic retn rn of.the levers K and of the pressing-beam H to allow of the insertion ofa book is effected by the spring M.

The cutting mechanism is illustrated in Figs. 7 and 8, Fig. 7 being a front elevation and Fig. 8 a side view, partly in section. The cutting mechanism is operated by the spur-wheel h, (see Fig. 1,) carrying the bevel wheel t, which drives the bevel-wheel k, on which is situated a crank-disk k, Figs. 7 alnd 8. The crank-disk k is connected by pins k with a draw-bar B, which. is attached at B to a beam B", which carries a knife B. The knife-beam B slides up and down in the frame and is guided by roller-pins in oblique slots or ways 13, Figs. 1 and 7. The rotation of the crank-disk k is changed by the connecting-rod B into a reciprocating motion, which causes the alternating ascent and descent of the knife-beam B and the knife B.

In consequence of the oblique slots B Fig. 1, the movement of the knife B is diagonal to insure a better cut. The knife B is arranged obliquely to the cutting-table and cuts support (shown also inFigs. 1 and 2) is de-' signed to give the necessary support to that receiver of the rotary feeding device which is below the cutting device against the pressure of the knife acting from above. In order to allow the rotary feeding device to continue its travel after the cutting operation, it is necessary that the cutting-support F retires to clear the path at the moment when the rotary feeding device is to continue its journey. This is eiiected by' the mechanism shown in Figs. 9 and 10. Acamd is situated on the axle which carries the bevel-wheel t. A lever F with a roller F, moves on the face of the cam d, against which it is pressed by a spring F9. The lever F rotates with the axle F The same axle carries a lever F which reciprocates, by means of aconnectingrod and lever F, the support F, situated on the axle F the movement being indicated'in dotted lines in Fig. [0. When the support F is to support the rotary feeding device, itpasses to the, left, Figs. 2 and 10, where it remains at rest until the edge of the book has been out. When this has been done, the eccentric presses the lever Ff and the support F back into the position shown in dotted lines in Fig 10, and the rotary feeding device has room to pass. The position of rest and the movement of the cutting-support F with the lever mechanism are obtained by the curves of the cam (Z. A brake R, Fig. 1, is provided,'sothat the rotary feeding device comes to rest on the support F without jar. The brake R is operated by a projection at the side of the rotary feeding device, which pushes the spring-pressed pin R to the left at each quarter-rotation. The 'pin' R is connected to a brake-lever R the ressure of which against the wheel R brakes;the mechanism.

Fig. 11 is a front view, and Fig. 12 is a transverse section, of a mechanism for coloring the edges of a book after they have been cut, said coloring mechanism not being claimed in this application, but is shown so that a better understanding may be had of the complete machine. This coloring mechanism consists, essentially, of a carriage 0, provided color or colors is printed on the cut edge according to the desired pattern of ornamenta 'tion.' In order to carry out the operation the color onto the edge of the book accordingto the raised pattern of the roller. The printing-carriage 0 runs by means of rollers 0 Figs. 11 and 12, on rails D and is suitably guided. It is reciprocated by a connectingrod 2, connected to the rotary crank-disk S, which, is operated by bevel-wheels r 1', situated on the axle q and operated by bevelwheels pp. The other driving mechanism has been hereinbefore described. The coloring devices for the cut edges of the book may be arranged in a different manner and in a different place. The carriage C may pass through the machine transversely instead of longitudinally.

Fig. 13 is a rear elevation,and Fig. 14 is a side view, partly in section, of the delivering mechanism. The delivering mechanism, which removes the book from the machine, consists of the oscillating lever E pivoted at E and operated by the crank a situated on the spur-wheel it, which latter is-operated by the spur-wheel u. 'The lever E is connected at the top with the-delivery-carr'iage E, which runs, by means of rollers, on rails N and is reciprocated on the latter,by the lever E to an extent indicated by dotted lines in the drawings. An adjustable arm E is arranged on the delivery-carriage E Fig. 14, and passes during its reciprocating journey through the receiver of the rotary feeding device, pushing the book out of the receiver from the side P of the machine to the side P, Fig. 13.
